De Havilland DHC-6-300 Safety Record

The failure of a ground handler to follow company proceedure/directives, and his premature release of a mooring line. Factors associated with the accident were the congested operations area, and the operator's failure to provide adequate safe zones for the airplanes.

the loss of power to both engines for undetermined reasons during approach. Contributing factors were the pilot's failure to properly position the fuel selector in accordance with the landing checklist and the lack of suitable terrain for the forced landing.

A failure of ground handling personnel to verify a release procedure/directive, and removal of the airplane's tiedown, and subsequent collision with a parked airplane.

The failure of maintenance personnel to correctly diagnose and correct a reoccurring nose gear steering problem, and the improperly tensioned nose wheel steering actuator cables which provided the pilot with an erroneous cockpit indication that the nose gear was centered when it was cocked.

the pilot's inadequate en route fuel consumption calculations, which led to his failure to recognize a deteriorating fuel duration versus time-to-go situation in a more timely way.

THE AIRPLANE'S CONTROLLED FLIGHT INTO TERRAIN AS A RESULT OF THE DECISION OF THE CAPTAIN TO CONTINUE FLIGHT UNDER VISUAL FLIGHT RULES AT NIGHT INTO INSTRUMENT METEOROLOGICAL CONDITIONS (IMC), WHICH OBSCURED RISING MOUNTAINOUS TERRAIN. CONTRIBUTING TO THE ACCIDENT WAS: THE INADEQUATE SUPERVISION OF PERSONNEL, TRAINING, AND OPERATIONS BY ALOHA ISLANDAIR MANAGEMENT AND INSUFFICIENT OVERSIGHT OF ALOHA ISLANDAIR BY THE FEDERAL AVIATION ADMINISTRATION PARTICULARILY DURING A PERIOD OF RAPID OPERATIONAL EXPANSION.
